DISH-WASHING MACHINE.

Specification 01 Letters Patent.

Patented Dec. 19, 1916.

Application filed October 3, 1912. Serial No. 723,687;

To all whom it may concern.

Be it known that'I, WILLIAM B. BARLEY, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Dish- Washing Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My invention relates to dish washing apparatus and it has for one of its objects to provide an improved construction and arrangement of parts for this class of machinery, which will lessen the amount of power required, and at once increase the capacity of the machine.

A further object of my invention resides in providing means for automatically elevating the dish holders, thus assisting in the operation of the machine by bringing the dishes readily to the top of the tank.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a partial side elevation of a machine constructed in accordance with a preferred embodiment of my invention; Fig. 2 is a vertical sectional view, on the line 2 a of Fig. 3; Fig. 3 is a longitudinal, vertical sectional view; Fig. 4 is a sectional view in detail, showing one of r the guide sprockets and the means for automatically controlling the same, and Fig. 5 is a detail sectional view illustrating the spring operating the guide sprocket.

Similar reference numerals throughout the several figures indicate the same parts.

' The invention, as disclosed in the present embodiment, includes a pair of receptacles or tanks 1 and 2, the adjacent walls of which are arranged in spaced relation to each other as indicated at 3 to afford an open space therebetween. Arranged for vertical movement within the receptacles 1 and 2 are the dish holders which may include the bottoms 4 connected by means of the links 5 to the side pieces 6 which engage the guideways 7.

The holders are adapted to support the I dish trays for vertical movement within the receptacles, the latter being preferably providcd, one with soapy" water and the other with rinsing water. To this end, a rock shaft 8 1s journaled between the receptacles near the lower ends thereof, as shown, and 1s provided with the upstanding portions 9 to which the levers 10 are attached. ()ne of the latter is preferably constructed with an upper handle portion 11 that is movable rel atively to the lower part, so as to permit it to be swung out of the way, when not in use. The parts 10 and 11 are held in operative position by means of the pins 12 and 13, which cooperate respectively with the slot 14 and the lower end 15 of the portion 11 as shown in Fig. 1. v

The dish holders are connected with the levers 10 by means of flexible connections 16, preferably in .theform of sprocket chains which pass over guides disposed at the'tops of the receptacles, herein shown as sprocket wheels, 17. The levers may be operated manually by the handle 11, or from a motor, and for the latter purpose, suitable connection may be made with the lever 10, at a point below the handle. When the levers 10 are moved back and forth, the dish holders, which have been previously loaded with dishes, are moved alternately up and down until thoroughly washed. By arranging the rock shaft 8 near the bottoms of the receptacles, I am able to obtain sufficient vertical movement of the dish holders with a comparatively slight movement of the levers 10, while at the same time the amount of power required for operating the latter is reduced to a minimum.

19 designate the removable dish trays while 20 are shelves attached to the upper ends of the receptacles for supporting the trays. I

In order to assist the operation of the machine as much as possible, it is desirable to provide means for automatically elevating the holders in the receptacles when they are empty, the arrangement being such Ithflt they will be lowered to the bottom only when fully loaded, and to this end, each sprocket wheel 17 is fixedly mounted on a stub shaft 21 journaled in the bearing 22. The bearing 22 is provided with a housing 23 which receives the coil spring24, one' end of the spring being connected to its housing and the opposite end to the shaft 21 whereby to normally effect rotation of the latter in one direction. The action of the spring is such as to rotate the sprocket wheel in a direction to elevate the dish holder, and

when the latter is fully loaded, it moves downwardly against the tension of the spring. The springs are .preferably so adjusted as to retain the holders in elevated position with a partial load of dishes, the lowering of the holders taking place only when a tray full of dishes is on the holder. It will be seen'from this that the automatlc elevating means just described assist materially in the operation of the machlne, since to raise the holders, only enough power is required to overcome the difference between the weight of the holder with its load, and the tension of the springs, and when both holders are loaded, one counterbalances the other.

I claim as my invention:

1. In amdish-washing machine, the combination with a pair of receptacles, of a holder movable within each receptacle, a lever fulcrumed between the receptacles, guides arranged at the tops of the receptacles, and flexible connections passing over the guides from the holders to said lever.

2. In a dish washing machine, the combination with .a pair of receptacles, of a holder movable within each receptacle, a lever fulcrumed between the receptacles, sprocket wheels arranged at the tops-of the receptacles, flexible connections passing over the cally elevate the holders.

3. In a dish washing machine, the combination with a pair of receptacles, of guides at the tops of the receptacles, a holder movable within each receptacle, means for elevating the holders comprising a lever fulcrumed at a point near the bottoms of the receptacles, and flexible connections between the lever and the holders, said connections passing around said guides and being attached to the lever at points adjacent to the plane of the tops of the receptacles.

L. In a dish washing machine, the combination with a pair of receptacles, of guides at the tops of the receptacles, a holder movable within each receptacle, a "lever fulcrumed at a point near the bottoms of the receptacles, flexible connections between the lever and the holders passing over said guides, and automatic elevating means operatively connected to the holders and acting to elevate the holders independently of said lever.
